Thought i would update as ive had a few days of playtime on this thing. Its not a SPL monster but still has impressive output. The sub is laughing at the kicker 500 though. Right now i have the box on 2" legs with sub firing down and port to driver side. I need to play with box positioning and maybe i can get it louder. It plays a wide range of frequencies well. On decaf it plays 28hz no problem and gets my windshield moving a bit. Then on pink floyd or gin blossoms ( clean tight bass btw) it sounds amazing.
Overall im happy with this. 60$ for the amp and if you add the amp, sub and all mats used to build box, Im under 200$. Dont think i could beat the output and clarity of this for that price any other way.
